TO ALL WI-IOM'IT MAY CONCERN:

l vBo it known that I, GEORGE BRUCE, of Corydon, Harrison county, andState of Indiana, have invented a now and useful Improvement inRoll-Carding Machines; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being had to theaccompanying drawing, forming part of this specification. i i

The nature of my invention relatos to a valuable improvement inroll-carding machines.' It principally consists in the simplicity andnovelty of thc feed works, they boing so constructedas to be nearlyautomatic in their operation, in spreading and feeding the wool from theapron to the machine, with `but little aid and assistp ance, while tofeed by the common device, requires the constant attendance of theoperator to spread and` regulate the feed of Wool from the apron to themachine. By myinvention, this'diiculty is obviated by the fact, that itmay be regulated so as to feed fast or slow as vthe nature` of thematerial may require.

To enablecothers skilled in the art, to make and use my invention, Iwill proceed to describe its constrlil'ction` and operation.

Figure 1 is a top plan view of my improved roll-carding machine.

Figure 2 is a side elevation of the same.

Letters of like name and kind referto like parts in each of the figures.

A is a rectangular frame, made of wood orA other material, upon which isplaced the machinery of my ro11- carding device. B and B are aprons,both of Evhich are attached to and run round rollers or shafts, c c c c,the said shafts are attached and workin the apron box, D, which isrigidly secured tothe front end of the frame, A. Upon the end of theshaft of the cylinder E, is a crank F, to which is attached a pitman,Gr, which is connected to the lever, H. At the top of this pitman G, isattached a cord, I, which passes back through the eye, J, and attachedto the key, K. To the lever H, is connected a pawl, L, which Works inthe ratchet-wheel, M. In, the ratchet-wheel also 4works the follower, N.Upon the shaft of the ratchet-wheel M, is a small pinion-Wheel, O, whichmeshes into the toothed wheel, P, upon the shaft of which is anotherpinion, Q, that meshes inta corresponding pinion, R,.which is securedupon the shaft C, that carries the apron, B. Upon the end of thecylinder E is a pulley, S, around which a band, T, Works over anotherpulley, U, upon` the end of the cylinder Y. Upon the end of the shaft ofthe cylinder E is acrank W, also another band-Wheel, a, around which theband b passes and over the band-wheel c, which is upon the shaft d.VTothese band-wheels are crank pins, ff, one ate'each end of the saidshaft. To each of the crank pinsf are connected the pitmen gg, `whichare' also connected to the crank 7L, which are attached to pendentlevers, it', which have a bearing upon each end of the` shaft of thecylinder V. p

The 'operation consists simply in supplying power to the crank W, Vwhichputs in moticn the cylinderE,

from which motion is given through the medium of pitman Gr and pawl L tothe ratchet-wheel M, from which motion is imparted to the toothed wheelI' and aprons B and- B', through the medium of the `pinion Q. 4 Motionis also impartedto the doer crank from the cylinderE through the mediumof the band b and pitman g. Now

it will be seen that as the wool is laid upon the apron B it is fedalong under the apron B', and is spread ot in suitable manner to enterthe machine. It will also be noticed that the feed vof Wool to the`machine may be varied-as desired by means of the key K and cord J. Whenthe feed is requiredto be slow, byturning ,upthe cord J around the key Kit reduces or shortens the stroke of the pawl L, which reduces the feedjust in proportion as the stroke of the pawl is reduced'. By theA motionof the comb the doiing cylinder V iskept clean, and `relieved from anyfibrous substance that may adhere thereto. Y

Having thus described my invention, whatI claim as new, and desire' tosecure byLetters of the United i States, isl p 1. The pitman G, 4pawl L,ratchet-whee1 toothed wheels O P, and pinions Q and R,`in`con1binationwith` the aprons B and B', for the purposeand substantially as hereindescribed.

I claim the manner of accelerating or reducing the feed by lengtheningorshortening the strokelof the` i pavgvl L by means of the lever G andcord J, substantially as herein set forth.A
